Answer:
B) $504
Explanation:
Given that the tickets cost half the price for both students and teachers , the addition of the number of students to the number of teachers multiplied by the cost of a ticket (now half the price given) will result in the total cost paid by the group.
Total number of teachers and students = 3 + 25
= 28
Half the given price = $36/2
= $18
Total ticket cost for the group
= $18 * 28
= $504
